8400 is the default communication port that is required for Proxy, MA and CommServe to communicate on. If there are port restrictions within the environment you will need to configure Commvault Network Routes to indicate to the Proxy, MA and CommServe to confirm which component will start the application tunnel (whether it is bi-directional or one-way)
How is the Network Routes configured between the Proxy and the Openstack VM?
Thanks for dropping msg here.
After opening support ticket, only I found out there are more ports required for backing up OpenStack environment. Those ports are not listed in BOL.
After webex session, I have requested end user to open up ports as listed, however still encountered below ports are required.
ERROR: Connect to CS:49956 failed: Connection refused
ERROR: Connect to CS:49937 failed: Connection refused
ERROR: Connect to CS:49992 failed: Connection refused
The final solution was reqesting user to open up all ports listed in logs and backup/restore are going through.
It is abit confusing when BOL does not state those ports out until a support ticket required. Just my personal opinion.
Thanks and regards,
